Patent DE-19636727-A1 (DE)
Inventor: KAJIKAWA YASUTOMO
IPC: H01L29/778
Filed: 1996-09-10
Abstract: A semiconductor device, such as a p-HEMT or a quantum well laser, includes a semiconductor base substrate (101 or 121) having a lattice constant and a surface; and a strained layer (3 or 24) grown on the surface of the semiconductor base substrate and comprising a semiconductor having a zinc-blende crystal structure with a lattice constant different from that of the semiconductor base substrate. The interface between the semiconductor base substrate and the strained layer is in a crystal plane which satisfies the relationship of (1 - * small Greek nu * cos 2 * small Greek alpha *)/cos * small Greek lambda * > 2(1 - * small Greek nu */4), where * small Greek nu * is the Poisson ratio, * small Greek alpha * is the angle between the Burgers vector and the dislocation line, and * small Greek lambda * is the angle between the Burgers vector and the direction in the interface, normal to the dislocation line, and the strained layer is epitaxially grown on the surface of the semiconductor base substrate without generating lattice-mismatch dislocations. When a strained InGaAs layer grown as described above is employed as a channel layer of a p-HEMT, the In composition of this layer becomes larger than that of a channel layer grown on a (001)-oriented substrate, without generating dislocations, whereby the electron mobility in the channel layer is increased and the noise characteristics in high frequency bands are improved. Further, since the thickness of the channel layer becomes thicker than that of a channel layer grown on a (001)-oriented substrate, without generating dislocations, the sheet electron concentration is increased, whereby the high-output characteristics of the p-HEMT are improved.

Patent DE-19640678-A1 (DE)
Inventor: FEHLMANN WOLFGANG
IPC: F02D1/18
Filed: 1996-10-02
Abstract: Disclosed is a fuel injection pump provided with a timing device piston (16) for timing beginning of injection and designed as a slaved piston for a slide valve (28) located therein. Said piston encompasses a working chamber (20) on one of its sides and is driven by pressure in said working chamber in opposition to the force of a return spring (23) and connected to a substantially fixed part of fuel injection pump cam drive. In order to avoid the effects of pressure backlash arising from kickback on the slide valve (28) and its setting, the inlet cross-section of connecting conduit is designed as an extended elongated cross-section which extends in the sliding direction of said slide valve. This enables trouble-free setting of the slide valve (28) and more precise vibration-free setting of timing device piston (16) and beginning of injection.

Patent DE-19652417-A1 (DE)
Inventor: LIPPERT GUNTHER DR
IPC: H01L21/336
Filed: 1996-12-09
Abstract: The present invention relates to a metal-oxide semiconductor transistor (MOS) with a doped silicon source-layer and a doped polycrystalline-silicon gate-layer, as well as the production of layers for use in such transistors. With the growing integration density, the structural sizes of the components tend to be reduced in the manufacture of semiconductors, especially the spacing between the various electrically active structures. Owing to the small spacing interactions occur between said structures, which should better be avoided if the semiconductors are to operate correctly. To solve that problem an additional electrically inactive material, preferably an element from the fourth main group, should be inserted into the inventive transistor, at least into one of its layers.

Title: Fault detector for vehicle catalytic converters
Inventor: KANG DAE-JIN
IPC: F01N11/00
Filed: 1996-12-30
Abstract: A fault detector to determine whether or not a vehicle catalytic converter (10) is working effectively consists of two oxygen sensors (11, 12), one at the inlet and the other at the outlet of the catalyser, an exhaust gas temperature sensor (13) and a motor cooling system temperature sensor (14). These are all linked to a control unit (20) and its display (30). The lean:rich ratio of the exhaust gas is calculated by the control unit on the basis of its oxygen content on entering and on leaving the catalyser, i.e. over a period of time, in relation to relevant temperatures. This is compared automatically with reference values and any abnormality sends a signal to the display, which consists of an alarm or warning lamp on the dashboard. Thus the operation of the catalytic converter can be checked while the car is in use.

Title: Passenger or goods transport using rail system
Inventor: BELLGARDT MARTIN
IPC: B61B13/00
Filed: 1997-01-10
Abstract: The transporting process involves the use of vehicles (10,30) on an elevated rail arrangement (59). A vehicle in the travelling position can overtake a vehicle in the waiting position, since the wheels (14a,b) of the vehicle in the travelling position can pass outside those (34a,b) of the vehicle in the waiting position. The vehicles can be raised or lowered vertically by the movement of turning arms (11a-31b) on axes (13a-33b) to take them from the raised travelling position to the lowered waiting position and vice versa. The wheels are further apart in the travelling position than in the waiting position.
